Overview
Fujinon HF-HA-1S series is a family of high-resolution machine vision lenses designed for 2/3-inch-type sensors with a target resolving capability up to 6.2μm pixel pitch. The DF6HA-1S model supports 1/2-inch-type sensors. The series succeeds the HF-HA-1B lineup while maintaining the same optical performance and mechanical dimensions.

Key features

• Resolution: supports sensors with up to 6.2μm pixel pitch (≈1.5 MP).
• Vibration- and shock-resistant mechanical design based on Fujifilm Anti Shock & Vibration Technology (patented); vibration test reference: JIS C 60068-2-6 conditions as indicated.
• High infrared transmission suitable for single-wavelength IR illumination in machine vision systems.
• Very short MOD on selected models (example: DF6HA-1S supports near 10 mm MOD from the front of the barrel).
• Compact, unified mechanical design: typical outer diameter φ29.5 mm (HF75HA-1S φ31.5 mm) and common user ergonomics across models.
• Wide lineup of 8 focal lengths (6, 9, 12.5, 16, 25, 35, 50, 75 mm) covering a broad range of industrial vision applications.
• Low F-number options on specific models (down to F1.2) for low-light conditions; manual focus and iris on all models.

Notes
The HF-HA-1S series is the successor to the HF-HA-1B series and maintains the same optical performance and mechanical dimensions. "Standard" sensor size indicates the ideal sensor to achieve target resolution; "max" indicates adaptable sensor sizes depending on model and application — check edge illumination and resolution for your setup.
